Ace hangers are convexed too which makes them a little but harder to get used to grinding street obstacles. They make them that way so you lock into grinds on your wheel, making them a good option for tranny, but they're a bit sketchy on rails and ledges.
And it's quite obvious that ace skate really loose and turny, but they're super stable. After you're used to them, all other trucks are going to feel tighter. I tried to get the same turn out of my Indys as I had on my ace so I loosened them up a bunch and I could barely ride for the first like half hour because they were so floppy. I like them now, but it definitely took some getting used to.
